AI Technical Summary

Technical Problem

The existing internal structure of flotation columns is insufficient for the dispersion of inhibitors and the contact efficiency between the slurry and bubbles, which affects the separation accuracy.

Method used

The flotation column internal separation component based on mercaptoacetate inhibitor is adopted. Microbubbles are generated by a microbubble generator, and a hollow shaft driven by an electric motor drives the cyclone tube to rotate, forming a strong turbulent environment, which allows the material to fully contact the bubbles. Combined with multi-layer guide plates, the material residence time is extended, thereby improving flotation efficiency.

Benefits of technology

It significantly improves flotation efficiency, reduces reagent usage, lowers operating costs, and enables continuous separation and slag removal, thereby increasing processing capacity.

Abstract

This utility model belongs to the field of flotation column technology, specifically relating to an internal separation component of a flotation column based on a mercaptoacetate inhibitor. It includes a cylindrical body, with a flotation seat connected to the top of the body. Multiple supports are welded to the upper end of the flotation seat, and a support base is fixedly connected to these supports. A motor is fixedly mounted on the upper end of the support base, with its output shaft passing through the support base and connected to it via a bearing. A hollow shaft is fixedly connected to the end of the output shaft, and a cyclone tube is connected to the shaft of the hollow shaft. The motor drives the hollow shaft to rotate the cyclone tube, which, combined with microbubbles generated by a microbubble generator, creates a highly turbulent environment, ensuring sufficient contact between the material and the bubbles, significantly improving flotation efficiency. Furthermore, the multi-layer guide plates extend the material residence time, and combined with the bubble adsorption effect, reduce reagent usage, thus comprehensively lowering operating costs.
